Network SSID:
The SSID differentiates one Wireless LAN group name from another;
so all access points and all devices attempting to connect to a specific
Wireless LAN group name must use the same SSID. A device will not
be permitted to join the BSS unless it can provide the unique SSID.
If the SSID parameter is “ANY”, it will detect the strongest signal of
the wireless station.

Channel:
It shows radio channel numbers that used for Wireless LAN
networking.

The channel number can be set only under the Ad-Hoc operation
mode. In Ad-Hoc mode stations, each station must have the same
channel numbers and SSID.
mode. In Ad-Hoc mode stations, each station must have the same
channel numbers and SSID.
In Infrastructure mode, the Wireless Cardbus Card will automatically
detect the channel number of the Access Point.
Security: the setting of the Network Encryption.
This function is used to protect wireless communication from
eavesdropping. A secondary function of encryption is to prevent
